New: DOE-HDBK-1233-2019, DOE Operations Security (OPSEC) Handbook

The protection of classified information, projects, and missions is of paramount importance in fulfilling security responsibilities in connection with the Department of Energy (DOE).

To ensure protection, employees should know and follow the applicable procedures and processes outlined in national and departmental policies.
